WICK LAMP BURNER Filed Feb. 26, 1937 J a a 9 a v n 71 f l 1 3a Patented Oct. 5, 1937 John Whiteman Morland Topley, Blackboys,

England Application February 26, 1937, Serial No. 127,991 In Great Britain March 6, 1936 V 3 Claims.

In wick lamp burners the wick, which is. ad-

' justable, as by a toothed wheel, up and down in a burner tube, is necessarily a fairly close working fit in the tube in order to obstruct escape of fumes and lighting back between the wick and the tube walls.

Owing to this comparative close fit, and also to the adjusting wheel or the like, which projects through the side Wall of thetube biting or engaging the wick, considerable difficulty is frequently experienced in feeding a new wick through the tube especially when slightly carbonized, it is also diflicult to clean the tube owing to its narrowness and to move the wick in or from the tube when threads or fibres of the wick have become entangled in the adjustive wheel or the like.

It is the chief object of the presentinvention to overcome such drawbacks and provide a simple, reliable and efficient burner such that a wick can be quickly and easily passed through the burner tube, that liability of escaping fumes and lighting back will still be avoided and that when required, the wick can be easily removed and the tube cleaned.

According to the present invention, the burner tube, through which the wick passes and which is furnished with a wick-adjusting device, is made somewhat wider or larger than the wick or the thickness thereof and is furnished with a removable packing piece, distance piece or the like, which is placed between the wick and the side wall of the tube.

By temporarily removing this packing or like piece a wick can be easily passed through or fitted into the tube without being interfered with by the adjusting ratchet wheel or other adjusting device and similarly a wick can be quickly removed. When the packing or like piece is in position, it mayalso serve to pressthe wick against the said adjusting mechanism. Should, as sometimes occurs an adjusting toothed wheel partially withdraw a thread or fibre from the wick and thereby cause a jam, this can readily be remedied by the withdrawal of the packing piece to free the wick.

The packing or like piece as applied to a burner tube for a flat wick is of awidth to extend completely along one side and within the tube and may be furnished at its upper end with a lip,

flange, clip or the like to facilitate its positioning and prevent it from slipping. This lip or the like may also serve as a means for withdrawing the packing piece, or an extension or other device may be provided on the upper end of the packing or like piece to facilitate the handling thereof.

The aforesaid packing piece may be fiat or provided with an offset part opposite or opposed to the adjusting wheel to press the wick against such wheel. It may also be rigid or of a springy or resilient nature. 5 A pressure screw or the like may also be provided to pass through awall of the tube to increase the pressure of the packing piece against the wick. With this arrangement the ordinary toothed or ratchet wheel for adjusting the wick may be replaced by a Wheel or disc having a milled or roughened edge which will be less: likely to damage the wick.

When employed with a curved wick holder, the packing piece will be similarly shaped.

When the burner tube is cylindrical and the wick is a tubular or a round one the packing piece may be in the form of a sleeve and the lower end or part thereof may be slotted for the passage of the wick-adjusting device. 20

The accompanying drawing illustrates by Way of example a wick lamp burner with a fiat Wick.

Fig. 1 is a side elevation; and

Fig. 2 a vertical section on the line 22 of Fig. 1. 25

, As will be understood the burner fitting is shown detached from its oil reservoir and without a chimney.

The burner fitting comprises a tubular part I adapted to fit the mouth of the oil reservoir, a chimney supporting gallery 2 and a burner tube 3 supported by upper and lower members 4 and 5 from the part I and gallery 2; a toothed wheel 6 for adjusting the wick is shown projecting through a slot 3 in the tube 3 and carriedby a spindle I mounted in bearings and extended to the outside of the fitting where, it has a milled head as is usual.

The burner tube 3 is of greater internal width than the thickness of the wicks 8 and a packing piece 9, shown solid, is inserted in the tube 3 after the wick has been threaded through it; the packing piece 9 is slightly extended laterally at each side to form lips 9 that rest on upper edges of the tube 3, these edges being cut down so that the top of the packingpiece 9 is level with the top edge of the wall of the tube 3 on the opposite side of the wick 8. The lips 9? extend beyond beyond the sides of the tube sufliciently to en.- able the packing piece tobe easily manipulated.

Any suitable catch device may be provided to prevent the packing piece 9 being raised when the wick is being raised; in the example the packing piece is formed with an indentation 9 and the wall of the tube 3 has a corresopndingly located indentation 3 which springs into the indentation 9' when the packing piece is in position.

The packing piece 9 can be easily pulled out of the tube 3, thus leaving plenty of room for insertion of the wick or for disengaging it from the wheel 6 furthermore, on removal of the packing piece and the wick, the inside of the tube can be easily cleaned or scraped by a knife or other tool. 7

What I claim is: V

1. In a wick lamp burner, the combination of an internally Wide burner tube, a thinner wick located at one side of the tube, wick-adjusting means extending through the wall of the tube, a removable packing piece located between the wick and the opposite wall of the tube and means for supporting said packing piece in position.

2. A wick tube burner comprising a flat burner tube of greater internal thickness than the wick and a solid packing piece located between the Wick and the opposite wall of the burner tube and adapted to be moved by hand into position in and out of said tube.

3. A wick tube burner according to claim 2 wherein the packing piece is formed with laterally extending lips resting on cut down top edges of the burner tube, the top of the packing piece then being at the level of the top of the wall of the tube on the opposite side of the wick.
